Mariners catching prospect batted .378 for last-place team

South Korean catcher Ji-Man Choi, who batted .378 for the last-place Mariners, on Tuesday was named Arizona League MVP.

Choi also ranked second in both on-base percentage (.459) and slugging (.541), collecting 17 doubles, a homer and 23 RBIs in 39 games before he was promoted to Class A Advanced High Desert.

While Choi was the only Mariner on the Postseason All-Star Team, the Royals and Rangers each placed three players on the 13-man squad.

Royals right-hander Robinson Yambati, who led the league with eight wins and ranked sixth with a 2.71 ERA, is joined by league saves leader Tyler Gatrell (1-0, 1.29 ERA, 12 saves) and first baseman Henry Moreno (.327, four homers, 32 RBIs).

Second baseman Nick Shaw, the Brewers' 25th-round pick in the 2010 Draft, fills out the infield after batting .339 with a league-leading .478 on-base percentage, 19 RBIs and 14 steals in 48 games.

The Brewers' other All-Star is left-hander Charly Bashara (5-2, 2.37), while Tony Diggs was named Manager of the Year after guiding the club to a 34-22 record and a first-place finish in the Central Division.
